Optimization of stellarator configurations combining omnigenity and piecewise omnigenity

Nuclear Fusion
We present a method for optimizing stellarator configurations that combine omnigenity and piecewise omnigenity (pwO). Within the OOPS optimization framework (Liu et al 2025 https://arxiv.org/abs/2502.09350 ), we introduce a mapping technique that can ...

Coil optimization methods for a planar coil stellarator

Nuclear Fusion
The planar coil stellarator design is a novel approach to producing the confining magnetic field of a stellarator plasma. The work presented here details the optimization of the two types of planar coils that are used in the planar coil design: the ...

ParaStell: parametric modeling and neutronics support for stellarator fusion power plants

Frontiers in Nuclear Engineering
The three-dimensional variation inherent to stellarator geometries and fusion sources motivates three-dimensional modeling to obtain accurate results from computational modeling in support of design and analysis of first wall, blanket, and shield (FWBS ...

Global fluid simulation of plasma turbulence in stellarators with the GBS code

Nuclear Fusion
The implementation of three-dimensional magnetic fields, such as the ones of stellarators, in the GBS code (Ricci et al 2012 Plasma Phys. Control. Fusion 54 124047; Giacomin et al 2022 J. Comput. Phys. 464 111294) is presented, and simulation results are

Influence of stochastic coil perturbations on magnetic configurations in Chinese First Quasi-axisymmetric Stellarator

Nuclear Fusion
Error fields resulting from deformations of coils are inevitable during fabrication, assembly and operation in all nuclear fusion devices. The magnetic topologies of stellarators are primarily produced by external coils, which are quite sensitive to ...
